Specification of Letters Patent.

Patented May 1909.

Application filed func 7, 1907. erm! No. 371,772.

T 0 all whom it may concern: l Be it known that l, DANIEL YVVARNER, a acitizen of the UnitedStates, residing at Bronson, in the county ofBranch, State of Michigan, have invented certain new and usefulImprovements in SpringWVheels, of which the following is a secification.

ThisinVentiOn re ates to improvements in The objects of this inventionare, first, to provide an improved spring wheel in whichthe elasticityof the spring members remains constant; that is, one in which it is notvariedbythe relative position of the springs in the wheel as the wheelrevolves. Second, to provide an improved spring wheel in which thespring members are so formed and arranged relative to the other parts ofthe wheel that each spring carries its share of the load, no matter whatits relative position in the wheel may be. Third, to rovide an improveds ring wheel adapted or use on motor vehic es, which is strong anddurable, and at the same time resilient, and one which is economical toproduce. Fourth, to provide an improved spring wheel in which an springcan be quickly and readil remover and another spring inserted, shou doccasion require, without disturbing the other parts of the wheel orwithout changing the tension of the 'lwheel.

Further objects, and objects relating to details of construction, willdefinitely appear from the detailed description to follow.

The objects of this invention are accomplished by the devices and meansdescribed 1n the fol owing specification.

The invention is clearly defined and pointed out in the claims.

A structure embodying the features of this invention is clearlillustrated in the accompanying drawing, ormin g a part of thisspecihcation, in which,

Figure 1 is a side elevation of a structure embodying the features ofthis invention, portions being broken away to show the arrangement olthe parts. Fig. 2 is a vertical central section, taken on a line corrcsonding to line 22 of Fig. 1, looking in the irection of the littlearrows at the ends of the section line. Fig. 3 is an enlarged detailsection showing the relation of the inner ends of the p ates carried bythe s okes.

plates at their outer edges.

In the draiiring, slml ar numerals of reference refer to similar partsthroughout the several views.

Referring to the drawing, the hub 1 of the structure herein illustrated,embodying the invention, is made of metal and is preferably providedwith an integral flange at one end and a removable flange at the other.These flanges are preferably made up of the flange members 2 and 2, theflange member 2 being the removable member, and the disklike flangeplates 3, which are arranged upon the hub between the flange "members2-2. The removable flange member 2 is sleeved uplon thchub, as clearlyappears in Fig. 2. e flange plates 3 are spaced by a plurality ofspacing members 3, the parts being clamped together by the bolts 4 and5, the bolts 4 being arran ed throu h the flange members 22 and theflange plates, and the bolts 5 being arranged through the flange Thespacing members 3 are sleeved upon the clamping bolts whereby the partsare held in position. This rigidly secures the flange members 22 and 3together forming, in effect, when the parts are assembled, a rigidconstruction. One of the hub-plates is provided with a plurality ofopenings which are closed by the ca s 9'.

he rim 11, which may be of any desired form, is preferably a channeledrim, having a suitable cushioned tirc 12 therein.

The spokes 6 are rigidly secured to the rim with their inner endsarranged between the hub-plates 3. On the inner ends of the spokes aretransverse openings 7 adapted to receive the spirally-coiled springs 8.These springs are secured to the p ates 3 by means of the bolts 9, whichare arranged to enga e the central coils of the springs, as clearyappears from the drawing. The bolts are a so preferably adapted-tosecure the caps 9 in place. When these caps are removed, the springs 8may be readily slipped out of the pockets in the spokes.

Between the spokes are arranged the guards 10. These guards are carriedby the spokes, the spokes being provided with rojecting lugs to whichthey are secure 1) means of screws 16. The spokes are all pro crablyconnected by a ring 13, which 1s arranged between the plates 3 andconnected to the inner ends of the spokes, preferably by the screws 14.

By arranging and supporting the springs as obviated, while the wheelsare capable of carrying very heavy loads and are very resilient and welladapted to absorb the jars. and

shocks of all kinds and carry the vehicle with a minimum amount ofvibration.

I have illustrated and described my improved wheel in detail in the formpreferred onaccount of the structural simplicity and convenience inassembling the parts, and

also the facility with which the springs may be readily removed in caseof injury thereto. I am, however, aware that it is capable ofconsiderable variation in details of construction without departing frommy invention,

a hub, having a fixed flange and a removable flange, said flanges comrising the flange members 2-2, and diskike flange plates 3, one of saidflange plates having a plurality of openings therein; caps for saidopenings in said flange plates; a rim; spokes having transverse openingsat their inner ends adapted to serve as spring pockets secured to saidrim, the inner ends of said spokes being arranged between said flangeplates; and spring connections for said spokes to said hub adapted to beinserted or removed through the said openings in said flange plates.

2. In a spring wheel, the combination with a hub, of a pair offlangessecured-thereto,

one of said flanges having a plurality of openings therein; caps forsaid openings in said flanges; a rim spokes having transverse openingsat their inner ends adapted to serve as spring pockets, secured to saidrim, the inner ends of said spokes being arranged between said flanges;spiral springs arranged in said pockets in said spokes; bolts arrangedto engage the central coils of said springs and retain said caps for theopenings. in said flanges in osition, and guards arranged between saispokes and, flanges.

flanges; a rim; spokes having transverse openings at their inner endsadapted to serve as spring pockets, secured to said rim, the inner endsof said spokes being arranged between said flanges s iral springsarranged in said pockets in sai spokes; and bolts arranged to engage thecentral coils of said springs and retain said caps for the openings insaid flanges in osition.

4. In a spring w ieel, the combination with a hub comprising a.' air offlanges, a rim, spokes rigidly secure to said rim the inner ends of saidspokes being fitted between said flanges to reciprocate between the sameso that they are supported against lateral movement thereby, said spokeshaving spring pockets in their-inner ends, spirally coiled springsarranged in said pockets, the

outer coils of said springs being secured to said spokes and their innerCOIlS being secured to said flanges by bolts'arranged therethrou 11,connections for the inner ends of said spo (es whereby they are securedto move in unison, and guard members carried by said spokes, said guardmembers being fitted to reciprocate. with said spokes between said hubflanges and lying normally at the periphery thereof.

5. In a spring wheel, the combination with a hub com risinga pair offlanges, a rim,

spokes rigir ly secured to said rim the inner ends of said spokes beingfitted between said flanges to reciprocate between the same so that theyare supported against lateral movement thereby, said spokes havingspring pockets in their innerends, spirally coiled springs arranged insaid pockets, the outer coils of said springs being secured to saidspokes and their inner coils being secured to said flanges by boltsarranged therethrough, and guard members carried by said spokes, saidguardmembers being fitted to reciprocate with said spokes between saidhub flanges and lying normally at the periphery thereof.

In witness whereof, I have hereunto set my hand and seal in the presenceof two witnesses;
